ABSTRAK Ni Putu Aryati Rinosta, Program Studi Magister Teknik Sipil, Program Pascasarjana, Institut Teknologi Nasional Malang, Januari 2026, Penerapan Cost Benefit Analysis (CBA) Pada Penanganan Rekonstruksi Jalan Nasional Waingapu-Melolo di Kabupaten Sumba Timur, Tesis, Pembimbing: (1) Dr. Ir. Nusa Sebayang, MT, (2) Ir. Maranatha Wijayaningtyas, S.T., M.MT., Ph.D Ruas jalan nasional Waingapu–Melolo di Kabupaten Sumba Timur memiliki peran strategis dalam mendukung konektivitas wilayah dan aktivitas ekonomi lokal. Namun, kondisi geometrik dan perkerasan jalan yang belum memenuhi standar serta kerusakan berulang menuntut adanya penanganan rekonstruksi yang tepat dan efisien. Penelitian ini bertujuan untuk mengevaluasi kelayakan ekonomi rekonstruksi ruas Waingapu–Melolo menggunakan metode Cost Benefit Analysis (CBA) serta menentukan alternatif perkerasan terbaik berdasarkan kinerja ekonomi dan analisis sensitivitas. Tiga alternatif perkerasan dianalisis, yaitu Laston Lapis Aus (AC-WC), Laston Lapis Aus A sbuton, dan Lataston Lapis Aus (HRS-WC). Analisis dilakukan dengan menghitung komponen biaya investasi dan pemeliharaan serta manfaat berupa penghematan biaya operasional kendaraan (VOC) dan penghematan nilai waktu tempuh (VOT) selama periode analisis 15–20 tahun. Data yang digunakan meliputi survei kondisi jalan, survei lalu lintas, data biaya konstruksi, serta proyeksi pertumbuhan lalu lintas. Evaluasi kelayakan dilakukan menggunakan indikator Net Present Value (NPV) dan Benefit Cost Ratio (BCR) dengan tingkat diskonto 5,27%. Hasil penelitian menunjukkan bahwa pada kondisi dasar seluruh alternatif menghasilkan nilai NPV negatif dan BCR < 1, sehingga secara ekonomi belum layak. Namun, alternatif Lataston Lapis Aus (HRS-WC) memiliki kinerja ekonomi terbaik dengan nilai NPV paling mendekati nol dan BCR tertinggi. Hasil analisis sensitivitas menunjukkan bahwa kelayakan proyek paling dipengaruhi oleh perubahan biaya. Pada skenario penurunan biaya 25%, alternatif HRS-WC menjadi layak secara ekonomi dengan BCR sebesar 1,057 dan NPV positif sebesar Rp. 481,34 juta. Penelitian ini menyimpulkan bahwa meskipun proyek belum layak pada kondisi dasar, alternatif HRS-WC merupakan pilihan paling efisien dan berpotensi layak apabila dilakukan pengendalian biaya secara signifikan.

ABSTRACT Ni Putu Aryati Rinosta, Master’s Program in Civil Engineering, Graduate Program, National Institute of Technology Malang, January 2026. Application of Cost Benefit Analysis (CBA) for the Reconstruction of the Waingapu–Melolo National Road in East Sumba Regency. Thesis. Supervisors: (1) Dr. Ir. Nusa Sebayang, M.T.; (2) Ir. Maranatha Wijayaningtyas, S.T., M.MT., Ph.D. The Waingapu–Melolo national road in East Sumba Regency plays a strategic role in supporting regional connectivity and local economic activities. However, the existing geometric conditions and pavement structure do not fully comply with applicable standards, and recurring pavement deterioration indicates the need for an appropriate and efficient reconstruction strategy. This study aims to evaluate the economic feasibility of reconstructing the Waingapu–Melolo road using the Cost Benefit Analysis (CBA) method and to determine the most suitable pavement alternative based on economic performance and sensitivity analysis. Three pavement alternatives were analyzed: Asphalt Concrete Wearing Course (AC-WC), Asbuton Asphalt Concrete Wearing Course (AC-WC Asbuton), and Hot Rolled Sheet Wearing Course (HRS-WC). The analysis involved calculating investment and maintenance costs as well as benefits derived from vehicle operating cost (VOC) savings and travel time savings (value of time/VOT) over an analysis period of 15–20 years. The data used in this study included road condition surveys, traffic surveys, construction cost data, and projected traffic growth. Economic feasibility was evaluated using the Net Present Value (NPV) and Benefit Cost Ratio (BCR) indicators with a discount rate of 5.27%. The results show that under baseline conditions, all pavement alternatives yield negative NPV values and BCR values below one, indicating that the project is not economically feasible. However, the HRS-WC alternative demonstrates the best relative economic performance, with the highest BCR and an NPV value closest to zero. Sensitivity analysis reveals that project feasibility is highly sensitive to cost variations. Under a scenario of a 25% reduction in costs, the HRS-WC alternative becomes economically feasible, achieving a BCR of 1.057 and a positive NPV of IDR 481.34 million. This study concludes that although the reconstruction project is not feasible under baseline conditions, the HRS-WC alternative represents the most efficient option and has the potential to become feasible provided that significant cost control measures are implemented.
